The Research On Eco-environmental Problems In The Urbanization Process Of Xinjiang Province

With the continuous development of population, economy and space urbanization in Xinjiang, the population has been constantly expanding into the urban agglomeration, the Space continues to expand in rural areas and The economy is growing, but it is accompanied by a series of ecological environment problems. "Industrial waste", urban sewage, solid waste made the Xinjiang ecological environment destruction, urbanization effects on the ecological environment is increasingly prominent. Therefore, in order to coordinate the development of urbanization and ecological environment in Xinjiang, do research on The ecological environment problems in the rapid development stage of urbanization, Put forward the corresponding countermeasures and measures to ensure the coordinated and sustainable development of urbanization and ecological environment.In this paper, urbanization, ecological environment and the interaction between urbanization and ecological environment as the main theoretical analysis tool, initially built in the relevant theoretical framework. And then Based on the theoretical framework, Analysis the present situation of Xinjiang urbanization and the ecological environment development. With the Coupling coordination model and GIS spatial analysis tools to analyze the coupling coordination of urbanization and ecological environment. At last, quantitative analysis of the main ecological environment problems such as the atmosphere, water, soil, the quality of human settlements and the effects of urbanization on species change and draw the corresponding conclusion:(1) From the ecological environment conditions: From 2004-2014 years in Xinjiang, Annual average annual concentration of PM10 exceeds the SO2 and NO2, This reflect the Xinjiang dust air pollution characteristics; At present Xinjiang water resources is shortage, With the development of urbanization, the use of water resources increased year by year, from 2000-2014 years, Xinjiang total water consumption, industrial water consumption, the per capita living water consumption is increasing, this condition bring a certain pressure to water resources; Compared to 2004 yer, 2014 Xinjiang cultivated land area increased by 708043.7 hectares. The construction land area have been expand, but the regional difference is great, and the Intensive utilization degree and land use efficiency is low.(2) Based on the urbanization and ecological environment coupling coordination degree model, do study on the comprehensive level of urbanization, ecological environment and the coupling coordination degree of around the city of Xinjiang, find that,from 2004-2014 years, the overall level of urbanization in Xinjiang 15 research areas showed a rising trend, but Individual regions and individual years, the comprehensive Urbanization development level was appeared a falling phenomenon; With the comprehensive development of urbanization in Xinjiang, the overall level of the ecological environment was also grew, but its volatility is relatively large, and the enhance of persistence is not strong; On the coupling degree, Although the coupling degree of each region is arranged with the fluctuation of numerical value in 11 years, but its coupling degree are maintained at more than 0.400 of the moderate coupling; The coordination degree between urbanization and ecological environment in Xinjiang has increased in time series, but there is no obvious level jump. Coordination degree is lower than the system coupling degree, and the whole is in a barely coordinated stage; In the space angle, based on GIS spatial analysis, It was concluded that the coordination degree between urbanization and ecological environment in the whole region of Xinjiang in 2004-2014 was significantly different, the overall coordination of the urbanization and ecological environment is higher than in South Xinjiang.(3) Overall speaking, Because Xinjiang is in the period of the development of Urbanization, The Urbanization caused by a great pressure to the ecological environment. With the economic urbanization, population urbanization and space urbanization, industrial wastewater, waste gas, solid waste, urban sewage excessive discharge to the ecological environment, made Xinjiang atmospheric environment, water environment, soil environment and living environment and other various overall quality gradually decreased, animals and vegetation quantity reduction or extincted. environmental issues gradually Outstanding, The relationship between urbanization and ecological environment became keen, so that the ecological environment protection and construction need to pay attention to and further strengthen. Therefore, in the process of rapid development of urbanization in Xinjiang, how to stop the deterioration of the ecological environment and promote the coordinated development of urbanization and ecological environment, sustainable development is particularly important.
